The Fire Phone isn't like other Android phones. It doesn't have the Play Store, nor does it come with Google's suite of apps. Amazon has customized its smartphone enough to look like a different platform, which is how it could get away with running Android 4.2 for so long.

But there are some features that Fire Phone users have had to do without (aside from the missing apps). With the latest jump from Fire OS version 3.6.8 to 4.6.1, that situation is changing. Amazon's handset now runs Android KitKat.

Android 4.4 brings support for Bluetooth Low Energy (commonly used in activity trackers and smartwatches), lockscreen notification improvements, printing, and other enhancements. KitKat is over a year and a half old, sure, but that's still newer than Jelly Bean.

Here's the changelog Amazon has provided.

  • Convert video clips into lenticular images and set HDR to auto: Record video clips and automatically convert them into a lenticular image to share with others or use on the lock screen.
